The DS4106, DS4212, and DS4425 ceramic surfacemount crystal oscillators are part of Maxim's DS4-XO series crystal oscillators family. These devices offer output frequencies at 106.25MHz, 212.5MHz, and 425MHz. The clock oscillators are suited for systems with tight tolerances because of the jitter, phase noise, and stability performance. The small package provides a format made for applications where PCB space is critical. These clock oscillators are crystal based and use a fundamental crystal with PLL technology to provide the final output frequencies. Each device is offered with LVDS or LVPECL output types. The output enable pin is active-high logic.
